ROBERT MORANT, OF LONDON, ENGLAND, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO JAMES KEMP WELOI-I, OF SAME PLACE.

GLASS OR PORCELAIN LINED METAL T-PIECE 0R ELBOW FOR PIPES.

SPECIFICATION forming part of Letters Patent No. 409,112, dated August 13, 1889. Application filed February 6, 1889. Serial No. 298,822. (No model.) Patented in England March 15, 1887, No. 3,907.

To all whom it may concern.-

Be it known that I, ROBERT MORANT, a subject of the Queen of Great Britain, residing at Regents Square, London, England, have invented a new and useful Improvement in the Manufacture of Glass or Porcelain Lined Metal T-Pieces or Elbows for Connecting Lengths of Similarly-Lined Pipes, (for which, jointly with Thomas Ernest Halford, I have obtained a patent in Great Britain, No. 3,907, bearing date March 15, 1887,) of which the following is a specification.

To enable this invention to be properly understood, I will proceed to fully describe the same, with the aid of the accompanying drawings, in which Figure 1 is an outside elevation of a T-piece constructed according to this invention; Fig. 2, a section of same; Fig. 3, a partial sectional view of parts embodied in Fig. 2, with necessary'additions thereto to enable the whole to be placed in a mold to have molten metal cast round; Fig. 4, a detached view of the glass or porcelain part previous to being covered by metal; Figs. 5 and 6, parts embodied in Figs. 2 and 3, hereinafter referred to.

I will proceed to describe the construction of a glass-lined T-piece according to this invention, the same manner being suitable, with necessary modifications, for the construction of elbows.

A glass T-piece A, as at Fig. 4, is first provided and then covered by metal as follows: A piece of preferably wrought-iron tubing of larger internal diameter than the outside of the glass, as at Fig. 5, has each end either screw-threaded with right and left handed threads or arranged for union-connections. In the middle of the tube a round piece B is cut out to leave a hole larger than the diameter of the glass. The tubeE is then divided in half at line a b, to form two pieces 0 D. These are put onto the glass T. Then another piece of tubing E, Fig. 5,is formed to fit on the remaining part of the glass and to cover the edges of hole B. These three pieces are held close together by rods F F, with outside nuts F the rod F screwing into rod F after the latter is inserted through T-piece A. These three pieces 0 D E are perinanently secured together by casting molten metal G round them for a certain distance of their length. To prevent the molten metal running through the joints of thepieces O D E, a coating of clay is placed between. The casting is done in a mold suitable for the molten metal used. To prevent the glass.

from cracking by the heat of the molten metal, it is arranged to be held off the inside of the pieces 0 D E. This can be done by means of washers H. After the pieces 0 D E have been secured by molten metal, as described, the washers are withdrawn and a suitable cement I pressed in between the outside of the glass and the inside of the metal pieces C D E, to entirely fill up the space. The T- piece is then placed in an oven to bake the cement hard, and finished by the runners and fins of the molten metal being removed in the usual way and the three ends ground to bring the glass, cement, and metal perfectly flush. The T-piece soconstructed is then ready for use. When connecting lengths of piping by these T-pieces, a suitable washer is placed between the ends of the T-piece and pipe. A suitable cement, as above referred to, maybe made of a mixture of Portland cement and plaster-of-paris mixed with water.

Having fully described my invention, what I desire to secure by Letters Patent of the United States is 1. A lined T-pieoe consisting of a glass part A, pieces of tube C D E placed on glass and fitting together and permanently secured by molten metal G, cast round, and cement I,

substantially as described.

2. A lined elbow-piece consisting of an inside glass part, pieces of tube placed on the glass having one end arranged to fit close together and permanently secured by molten metal G, cast round, and cement I, substantially as described.
